Description

Technical Field

[0001] The utility model relates to the technical field of tensioner equipment, in particular to a coil spring tensioner with a protection mechanism. Background Art

[0002] The mainspring is a special form of coiled spring that plays a specific role in transmission and energy storage in mechanical devices. During the production process of the mainspring, the elasticity and mechanical properties of the mainspring are generally tested through a tensioner. During the test, the two ends of the mainspring are connected to the driving end of the tensioner through a slot, and then the driving end drives the mainspring to reel.

[0003] However, in the prior art, due to the different quality of the mainspring, the connection between the mainspring and the slot is easily shaken by force after a long period of measurement during testing, resulting in falling off. At the same time, part of the mainspring breaks, causing the mainspring to pop out of the tensioner, causing nearby workers to be injured or equipment to be damaged, thereby causing defects. Utility Model Content

A coil spring tensioner with a protective mechanism is proposed to solve the technical problems of defects.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a coil spring tensioner with a protective mechanism, comprising a bottom support plate, a control computer is arranged on one side surface of the bottom support plate, a motor is fixedly connected to the lower surface of the bottom support plate, the output end of the motor is observed and connected to the upper surface of the bottom support plate, a protective cover is fixedly connected to the upper surface of the bottom support plate, an adjusting piece is embedded on the inner wall surface of the protective cover, a two-way bearing is fixedly connected to the lower surface of the adjusting piece, a protective plate is fixedly connected to the lower surface of the two-way bearing, a first clamp is fixedly connected to the inner wall surface of the protective cover, and a second clamp is fixedly connected to the output end of the motor, a first adjusting groove is opened on one side surface of the adjusting piece, one end of the second clamp is embedded in the first adjusting groove, a second adjusting groove is also opened on the upper surface of the adjusting piece, and the outer surface of the first clamp is embedded in the second adjusting groove.

[0006] Furthermore, a support groove is formed on one side surface of the protective cover, a positioning block is embedded in the support groove, and one side surface of the positioning block is fixedly connected to the outer surface of the adjusting member.

[0007] Furthermore, a guide block is fixedly connected to one side surface of the protective plate, a slide groove is provided on the inner wall surface of the protective cover, and an outer surface of the guide block is embedded in the slide groove.

[0008] Furthermore, four support brackets are fixedly connected to the lower surface of the protective plate and the upper surface of the bottom support plate, the four support brackets form a group, and the two groups of support brackets are equidistantly distributed.

[0009] Furthermore, a protective cover is fixedly connected to the lower surface of the bottom support plate.

[0010] Furthermore, a cover plate is fixedly connected to the upper surface of the adjusting member.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, during detection, the mainspring is sleeved on the outer surface of the motor output end, and then the two ends of the mainspring are respectively embedded in the corresponding first clamp and the second clamp, and then one end of the adjusting member and the protective plate are embedded in the protective cover, and the computer is controlled to control the motor to rotate so that the mainspring is wound. After reaching the specified stroke, the motor stops working, and the mainspring drives the output end of the motor to rotate in the opposite direction. The above operation is repeated. When the mainspring breaks or detaches from the first clamp and the second clamp, the protective cover and the protective plate prevent the mainspring from popping out, thereby preventing personal injury and equipment damage, ensuring safety during use, and improving the user experience.

[0013] 2. In the utility model, by rotating the adjusting piece, the position of the positioning block inside the support groove is controlled, and the distance between the adjusting piece and the bottom support plate is adjusted. It can be suitable for springs of different specifications. The protective plate does not rotate.
